The following notes describe the porting of Tim Pearson's PGPLOT 5.1.0
to Microsoft Windows95 (or WindowsNT), using Microsoft PowerStation 
Fortran 4.0.  This 32-bit operating system is easy to use, but most 
importantly removes the severe memory restrictions of DOS.  The size of 
applications which can be linked with PGPLOT.LIB is limited only by 
total physical and virtual memory.  The MSFLIB Library also includes 
many additional (system) functions known from C.  Even for an  
old-fashioned command-line Fortran programer (like PAS), it is  
relatively easy to add features like dialog boxes and custom menus.

Once PGPLOT.LIB is built, applications are most easily compiled using 
the Microsoft Developer Studio.  The application type must be "QuickWin",
or it must be compiled with command line option "/MW".  Programs execute 
in a text window, with the graphical output in up to 8 separate child 
windows.  Cursor functions (including rubber-band modes) are implemented 
with the mouse. 
NOTE: applications developed in this Fortran will NOT execute under 
      DOS or Windows 3.x (no, not even with WIN32s).

The steps in building PGPLOT.LIB are the following: 

1. Download PGPLOT 5.1.0 by your favorite method.  Don't be fooled by the
   ".ZIP" file, which is Macintosh.  I decompressed ver. 5.0.3 on VAX-VMS 
   system, and ver. 5.1.0 from a Unix machine ("uncompress" followed by
   "tar -xcf").

2. Create an appropriate subdirectory structure; e.g.
     x:\PGPLOT
              \SRC
              \SYS_Win
              \DRIVERS
              \FONTS
              \EXAMPLES
   and copy files from the corresponding subdirectories of the downloaded
   file.  Delete file GRGFIL.F from \SRC, or else overwrite it with the
   version of GRGFIL.F from \SYS_Win.  (Personal preference note: I also 
   copy \APPLICAT\PLOT10\PLOT10.F into the \SRC subdirectory.)  File
   GROPEN.F also needs modification; put this BLOCK DATA at the front and 
   delete the DATA statement for GRSTAT in the declaration section:
      C*GROPEN -- open device for graphics
            block data
            include 'grpckg1.inc'
            data GRSTAT/GRIMAX*0/
            end
      C+
   The files in \SYS_Win should include
      AAAREAD.ME (this file)
      GRDOS.F
      GREXEC.F
      GRGFIL.F
      GRSY00.F   (not system dependent)
      W9DRIV.F   (the driver itself, with attached subroutines)

3. On your boot disk (almost surely C:), create a directory C:\PGPLOT
   and copy RGB.TXT to it.  You also need to compile and execute the
   program PGPACK in subdirectory \FONTS to convert file GRFONT.TXT to
   GRFONT.DAT, and copy or move GRFONT.DAT to C:\PGPLOT.  (The directory 
   with these two files can be elsewhere if identified by environment
   variable PGPLOT_DIR, or the full [path]filenames can be given in
   PGPLOT_RGB and PGPLOT_FONT.)

4. In the Developer Studio, in the File/New menu, Create a new Project 
   Workspace of Type "Static Library", Name PGPLOT, Location 
   x:\MSDEV\PROJECTS\.  Use the Insert/"Files into Project..." search 
   box to associate the following files with the project:
      x:\PGPLOT\SRC\GR*.F
      x:\PGPLOT\SRC\PG*.F
      x:\PGPLOT\SRC\*.FOR
      x:\PGPLOT\SYS_Win\*.F
      x:\PGPLOT\DRIVERS\LXDRIV.F,NUDRIV.F,PSDRIV.F
   (The dependent *.INC files will be included automatically.)

5. Build the project.  From the Build menu, choose "Build PGPLOT.LIB".  
   The default compiler options are suitable; in particular, the Debug 
   configuration is not optimized, but the Release configuration uses
   full optimization.  Expect 7 Warning messages.  When successfully 
   completed, I like to copy the Release version of the library from 
   x:\MSDEV\PROJECTS\PGPLOT\RELEASE to x:\MSDEV\BIN, where subsequent 
   applications can find it easily.  

6. Run the examples.  In the same Project Workspace, use Insert/
   "Project..." to Create a project of Type="QuickWin Application",
   Name EXAMPLES.  Then use Build/"Subprojects..." to specify that 
   PGPLOT is a subproject of EXAMPLES.  One at a time, use Insert/
   "Files into Project..." to select a file from x:\PGPLOT\EXAMPLES.
   (The previous file may be deleted from the FileView window when
   successfully completed.)  From the Build menu, choose "Execute
   EXAMPLES.EXE".  You may delete all of the PGPLOT folders from 
   x:\MSDEV\PROJECTS after successfully testing the library.

7. Drivers for Windows95, Postscript, LaTeX, and the Null driver
   have been included. If you add additional drivers (which may require 
   debugging to eliminate perceived syntax errors etc.) to the library, 
   then subroutine GREXEC.F must also be modified to reflect the changes; 
   in particular NDEV must reflect the total number of drivers.
   The default graphic window size for device type "/W9" is 800*600 with 
   236 colors (SVGA).  The default can be changed by setting an 
   environment variable (either in AUTOEXEC.BAT, or from a command line
   before starting the application) as follows: 
      SET PGPLOT_VIDEO=VGA  (or V),   640 * 480
                       SVGA (or S),   800 * 600
                       XGA  (or X),  1024 * 768
                       ZGA  (or Z),  1280 * 1024
   Modes may also be selected by using alternate device types
   "/WV", "/WS", "/WX", or "/WZ".  Modes exceeding the capability of the
   Windows screen driver will be reduced to the maximum available.  For
   an example of the 236-color modes, see PGDEMO4.  For an example of
   different resolutions, try using "/WV" for the first window and
   "/WX" for the second window in PGDEMO13.

8. The cursor is emulated by an interrupt driven mouse routine (see
   GRW901 in file W9DRIV.F).  The cursor moves continuously whenever
   the window is selected, but the position is not returned to the
   calling program until a key has been struck, and the character is
   also returned.  Control then returns to the "text" window for any
   additional input or processing.  If you lose track, there is a status 
   message at the bottom of the frame window which tells you which 
   window is waiting for input.  The color of the cursor may be dim 
   against some backgrounds (especially green in the default palette), 
   but you can usually see it at the tip of the mouse arrow while you  
   move it around.  You might try using PGBAND mode 7 for the cursor to
   improve visibility.  See especially programs PGDEMO5 and PGDEMO6.

9. Plots can be clipped and copied to other applications, such as Word.
   Unfortunately, black is black and white is white, so printing uses a
   lot of ink and the white lines tend to disappear.  One option is to 
   exchange palette colors 0 and 1 in PGPLOT with 
      CALL PGSCR(0, 1., 1., 1.)    !black becomes white
      CALL PGSCR(1, 0., 0., 0.)    !white becomes black
   before making the version to be printed; another is to cut and paste 
   to a utility (I use Paint-Shop-Pro) in which you can adjust the color 
   palette; and a third way is to specify the "/PS" device and write a
   file.  (Note: this might be a good use for a custom menu entry in
   your application.)  Yet another option is to create a second device
   window and change the color palette only in that window.  (See 
   PGDEMO13 for an example of multiple simultaneous windows.)

10. Finally, this port has been thoroughly tested (starting with earlier
   versions of PGPLOT, through version 5.0.3), but no responsibility for 
   any damages is accepted (by either [PAS], [CTD], or even [TJP])!
